Current
Definition
Current refers to the flow of electrical charge in a circuit. It is measured in amperes (A) and represents how many electrons pass through a specific point per second.
Analogy
Think of current as water flowing through a pipe. The rate at which water flows through the pipe is similar to the flow of electrons in a circuit. Just like increasing water pressure increases flow rate, increasing voltage increases current.
Related terms
Voltage: Voltage, also known as electromotive force (EMF), is the driving force behind electron flow in a circuit.
Resistance: Resistance is any factor that opposes or restricts the flow of current in a circuit. It can be compared to obstacles that slow down water flow in pipes.
Ohm's Law: Ohm's Law states that there is a direct relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = I * R.
